Whew! Got rid of all the common arrange/acts as these tests really didn't need them. Only one test might need test class per fixture pattern (the first). The rest really needed to have their own isolated fixtures.

I'm not a huge fan of ObjectMother, I'd rather use AutoFixture in this case, or Fubu's way of object builder specifications for complex domains.

One other thing - when a test fails here, I can use standard IDE tools to navigate to type/member. With strings as keys representing test methods, I'm relegated to grep tools (not in my IDE) or "Find in Files" (much, much clunkier).
